摘要
针对目前交流电源电压技术的发展需要,以单片机为控制器,采用过零检测技术和触发技术,控制变压器次级各种绕组的不同组合产生所需要的输出电压,以达到对交流电源电压的调节。结果表明,本系统可以以0.5V的精度进行电压调节,实现了对交流电源电压的输出控制,可以输出工业或实验室中通常要用到的各种电压值的交流电源,能满足一些特殊的工作过程或实验的需要。
According to the need of development of AC mains voltage technique at present, using single-chip computer as the con- troller, adopting zero-crossing detect and triggering technique, output voltage needed is produced by controlling various assemblage of winding of voltage transformer secondary in order to adjust AC mains voltage. The result shows that, this system can be adjusted by the accuracy of 0.SV which implement the output-control of AC mains voltage, and can output various AC voltages often used in industry and experimental laboratory, satisfy some specific working process or the need of experiment.
